【Abstract】 This paper expatiates the thoughts of data mining with embedded knowledge and the techniques status quo of data mining. Based on the thoughts and the grey system (GS) theory, it proposes the GS\|based data mining method set (GDMS) for time sequence first. Then this paper introduces the idiographic arithmetic with GM(1,1) as an example. Last, it forecasts the total homes connecting with Internet in Shanghai in 2002—2005 by the arithmetic. [更多还原
